Description

  The present invention relates to a beverage container, and more particularly to an improvement of a beverage container having a drinking mouth (spout).

BACKGROUND OF THE INVENTION Beverage containers used by suckling infants are widely used in a form in which a cap with a flexible artificial nipple is attached to and detached from a container body that is a baby bottle.
A combination of a flexible artificial nipple body and a rigid cap that can be attached to and detached from the opening of a baby bottle made of glass or the like has also been proposed.

The cap disclosed in Patent Document 1 is formed by heat-sealing a cap body made of a relatively hard material such as polypropylene and a nipple body formed of a soft rigid resin such as an elastomer between different kinds of resins.
Since it has such a structure, there is no need to attach caps and nipple bodies that are individually formed on the baby bottle body (not shown), and it can be washed together during washing. Is excellent.

However, in transition from the time when infants take breast milk or artificial milk by suckling, in parallel to these, or after them, in order to ingest other drinks such as fruit juice as they grow, A spout that is suitable for taking a larger amount of liquid than an artificial nipple, and that has a structure similar to that of an artificial nipple. (Sucking mouth) is required.
However, the thing of patent document 1 is fundamentally for feeding, and there is no ventilation hole which enables the infant and the inside of a baby bottle to ventilate during drinking, and adjusts the tightening strength of the cap body 2. Since the ventilation is limited, the amount of ventilation is limited, and it becomes difficult to drink as the infant develops.

Then, the drink container which combines a spout and an artificial nipple is also proposed for the purpose of using at the transition time from nursing (refer patent document 2).
The beverage container described in Patent Document 2 includes a specially shaped artificial nipple.
The artificial nipple is made of a flexible material and includes a nipple that is formed at a position eccentric to one side and a restricting portion that bulges on the other side.

Japanese Patent No. 2741868 JP 2000-288

In the beverage container shown in Patent Document 2, when used for infants at the time of sucking, the nipple can reach the baby's sucking cavity and can be drunk in the same manner as when using a normal baby bottle. it can.
On the other hand, when the upper and lower lips are rotated in the opposite direction, the upper lip of the infant hits the front end of the restricting portion, so that the insertion depth into the oral cavity is restricted and it can be used like a spout. is there.
However, in this beverage container, the cap part to be attached to the bottle body has a structure in which the artificial nipple is sandwiched between the hard support part and the ring-shaped base part, so the number of parts is large. Has the disadvantage of being complicated.
Further, when assembling after washing, an assembly error due to a large number of parts, that is, a tightening failure is likely to occur, and liquid leakage may occur.

  The present invention has been made to solve the above-mentioned problems, and has a function suitable for shifting from a feeding movement, is easy to handle in washing and the like, and is easy to assemble. An object is to provide a beverage container that does not have the risk of losing food.

  According to the first aspect of the present invention, the beverage has a container body having an opening at the top, and an adapter attached to the container body so as to cover the opening to open and close the opening. The adapter has an adapter body and a spout part provided on the adapter body, the adapter body and the spout part are formed integrally, and the adapter body is The spout portion is formed of a soft material and is eccentrically arranged on one side of the adapter body, and is spaced apart from the spout portion on the other side of the adapter body. This is achieved by a beverage container provided with a ventilation portion formed of a soft material, and the ventilation portion is formed integrally with the adapter body.

According to the configuration of the first invention, the spout part made of a soft material and the ventilation part made of the same soft material are integrally formed on the adapter body made of a relatively high rigidity material. When disassembled, the number of parts is small and handling is easy.
In addition, when parts made of different materials are formed separately, tightening is possible only after proper assembly, and unlike conventional structures where sealing is performed, it should be formed of a soft material due to the demand for the function to be performed. Since the part and the part to be formed of a relatively rigid material are integrally formed, there is no fear of liquid leakage due to assembly errors.
Further, since the ventilation portion is formed away from the spout portion, when the infant inserts the spout portion into the oral cavity, appropriate ventilation is achieved without blocking the ventilation hole with the upper lip or the like. The liquid can be taken in at an appropriate flow rate.

According to a second aspect of the invention, in the configuration of the first aspect of the invention, the spout portion and the ventilation portion are integrally connected.
According to the structure of 2nd invention, the said spout part and the said ventilation | gas_flowing part are connected integrally. Since both the spout part and the ventilation part are formed of a soft material, they are different materials from the adapter body. Therefore, after the adapter body is formed of the first material (material having relatively high rigidity), when the spout portion and the ventilation portion are to be formed of the second material (soft material), they are integrally formed. Since they are connected, these formations can be formed from a single gate in a single molding.
Moreover, since the spout part and the ventilation part are integrally formed, even if there is a problem that the ventilation part is detached from the adapter main body, it is held by the spout part and there is no fear of aspiration.

According to a third aspect of the present invention, in the configuration of the first or second aspect of the invention, a hood portion that covers the adapter body is provided, a liquid passage hole is formed at a tip of the spout portion, and the ventilation portion is The adapter main body is formed so as to be recessed from the top surface, and the hood portion inner surface is provided with a liquid passage hole closing portion and a ventilation closing portion that enters the recessed ventilation portion.
According to the structure of 3rd invention, when putting a liquid in a container main body and carrying it, the liquid leakage from a spout part and a ventilation | gas_flowing part can be reliably prevented only by mounting | wearing a hood part.

According to a fourth aspect of the present invention, in the configuration according to any one of the first to third aspects, the adapter body includes a drinking opening and a ventilation opening, and the spout portion and the ventilation portion include The drinking opening and the ventilation opening are respectively covered and integrally formed on the inner surface of the adapter body.
According to the structure of 4th invention, since the said spout part and the said ventilation | gas_flowing part are connected, it can not only be formed by one shaping | molding, but since it is integrally connected inside the spout main body, the integral molding part is It is firmly fixed and is not easily damaged.

Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings.
The embodiments described below are preferable specific examples of the present invention, and thus various technically preferable limitations are given. However, the scope of the present invention particularly limits the present invention in the following description. As long as there is no description of the effect, it is not restricted to these aspects.

1 and 2 show the entire beverage container according to an embodiment of the present invention. FIG. 1 is a schematic perspective view showing a state in which the hood portion of the beverage container is separated, and FIG. 2 shows the hood portion of the beverage container. It is a schematic sectional drawing in the mounted state.
As shown in these drawings, the beverage container 10 includes an opening 11a on the upper surface (upper portion) and includes a container body 11 that can accommodate a beverage therein. The container body 11 is formed of a molded product of glass or synthetic resin, and is provided with a large opening 11a so as to perform cleaning after drinking, liquid injection, and preparation of milk powder or the like inside. Has been made easier. A screw portion is formed on the outer periphery of the opening portion 11a so that it can be attached to and detached from the adapter main body 14 of the adapter 15.

As shown in FIG. 2, a ring-shaped packing 27 made of silicone or elastomer is interposed between the adapter main body 14 and the container main body 11 so that the liquid can be attached. Denseness is ensured. The ring-shaped packing 27 is formed with tongue-shaped convex pieces 28 and 28 protruding inward at two locations on the circumference thereof. Since the convex pieces 28 are provided at two positions on the circumference and opposed to each other, they can be easily picked and attached and easily grasped visually, so that forgetting to wear them can be prevented. In addition, the packing 27 may be formed integrally with the adapter main body 14, and may be formed integrally with a spout portion 12 and a ventilation portion 13 which will be described later.
On the outer surface of the bottom of the container body 11, for example, an anti-slip 16 that is partially covered with a resin such as an elastomer is provided.

The adapter 15 includes an adapter main body 14, a spout part 12, and a ventilation part 13.
The adapter body 14 is formed of a relatively high rigidity material, in other words, a hard material, and for example, a synthetic resin such as polypropylene or polycarbonate is used. The adapter main body 14 has a flat circular lid shape or cap shape, and in particular, the upper surface (top surface) is formed horizontally and the thickness direction (Z direction) is formed as small as possible. ing. A pair of handles 17 and 17 that are slightly curved on the outer periphery of the adapter main body 14 and extend obliquely downward at an angle of about 25 degrees with respect to the vertical line as shown in FIG. Are integrally formed.

  As shown in FIG. 2, at least two openings, a drinking opening 21 and a vent opening 22, are formed in the adapter body 14. The drinking opening 21 is formed so that its center is slightly decentered with respect to the adapter main body 14 to the right (inclination direction of the handle 17) in the drawing. The drinking opening 21 is formed so that the spout portion 12 enters and is integrated, and the drinking opening 21 has a large opening in order to ensure sufficient outflow of the liquid to be drinked. On the other hand, the ventilation opening 22 is formed at a position separated from the drinking opening 21 to the left (opposite to the tilting direction of the handle 17) in the drawing, and has a volume of liquid that is consumed during drinking. The opening is made as small as possible so as to ensure the passage cross-sectional area required for the corresponding air intake.

The drinking opening 21 of the adapter body 14 is provided with a spout part 12, and the ventilation part opening 22 is provided with a ventilation part 13.
The spout part 12 and the ventilation part 13 are integrally connected by a band-like connection part 23, and are made of a soft material as a whole, for example, an elastomer such as a hydrogenated styrene isoprene copolymer resin or a styrene butylene copolymer resin, or silicone. Etc. are formed.
The spout portion 12 has an outer shape substantially the same as that of a specially shaped artificial nipple proposed by the present applicant in Patent Document 2, and includes a bulging portion 12a.
In addition, the form of the spout part 12 may be made into other forms, such as a nipple shape and a straw shape, as long as it has an appropriate flow rate and hardness as a spout.

The spout portion 12 is formed of a flexible material having an A hardness of about 40 degrees, and has a mouthpiece portion 12b formed at an eccentric position on one side and a bulging portion 12a bulged on the other side. At the tip of the spout portion 12, for example, a slit hole 12c that is a liquid passage hole is formed.
For example, as shown in FIG. 2, the ventilation portion 13 has a substantially U-shaped cross section in which the extended end of the flat connecting portion 23 is protruded downward while maintaining the same material thickness, and the ventilation inner wall 13 a whose upper surface is recessed. It is a valve body having, for example, a slit-shaped air hole 13b at the protruding tip, which is a letter-shaped or hemispherical portion. When the pressure in the container main body 11 decreases with drinking, the vent 13 is opened to allow the outside air to flow into the container main body 11 from the outside. In addition, the ventilation part 13 should just function as a valve body, for example, is good also as a valve body combined with the other moving member.

The adapter main body 14, the spout part 12, the ventilation part 13 part, and the connection part 23 that connects the spout part 12 and the ventilation part 13 part are integrally formed. In this case, after the adapter body 14 is formed of a relatively rigid first synthetic tree material, in other words, the spout portion 12, the ventilation portion 13, and the connecting portion 23 are made of a soft second synthetic resin material. The whole is integrally formed by insert molding or two-color molding. Thereby, since the spout part 12 and the ventilation | gas_flowing part 13 are integrally connected by the connection part 23, it can form by one shaping | molding from one gate.
Moreover, as shown in FIG. 2, the spout portion 12 and the ventilation portion 13 formed of a relatively soft material are integrally connected by a connection portion 23 inside the spout body 14, and further, the spout portion 12 and the ventilation portion. Since the base end portion of the portion 13 is formed so as to sandwich the drinking opening 21 and the ventilation portion opening 22 from above and below, the integrally formed portion is firmly fixed and hardly damaged.
Note that the gates of the spout portion 12 and the ventilation portion 13 may be provided separately, and may be formed at the same time even at separated positions, or may be formed by forming each by three-color molding or the like.

The hood portion 31 shown in FIG. 1 is formed of, for example, a transparent synthetic resin as a whole, and is fitted to the fitting convex portion 25 formed on the upper surface of the adapter main body 14 with the fitting convex portion provided on the inner bottom surface of the hood portion 31. It is mounted by fitting the part 31a.
The hood portion 31 has a dome shape as a whole, and the top surface 34 is preferably formed on a flat surface. For this reason, the food | hood part 31 can be made independent by making the top surface 34 into a bottom face on a table surface etc. by making the upper and lower sides of FIG. 1 upside down. The inner surface of the top surface 34 is configured to come into contact with the slit hole 12c when the hood portion 31 is mounted, and functions as a liquid passage hole closing portion.
Further, one surface of the hood portion 31 has an inclined curved surface 35 that is cut off. Thereby, the hood part 31 becomes a form by which the directionality is visually recognized.

A recess 33 is formed near the lower end of the inclined curved surface 35 of the hood portion 31. From the bottom part of the recessed part 33, the ventilation closing part 32 which protruded below thinly is formed. The ventilation closing portion 32 has a cross-sectional shape similar to the ventilation inner wall 13a, and has a slightly larger diameter than the ventilation inner wall 13a.
On the other hand, as shown in FIG. 3, on the upper surface of the adapter main body 14, the outer side of the region 26 made of a soft material including the spout portion 12 and the ventilation portion 13 has a slight height so as to surround the region 26. The fitting convex part 25 is provided so that the step part may be formed.

The outer shape of the fitting convex portion 25 corresponds to the inner circumference of the bottom portion of the hood portion 31 and is an ellipse or an egg shape with one end slightly sharpened as shown in FIG. It is designed to prevent incorrect installation. For the same effect, a projecting portion that projects in one direction may be formed on the fitting convex portion 25 side and the inner periphery side of the hood portion 31 to define the mounting directionality.
As shown in FIG. 2, the hood portion 31 is always mounted correctly on the adapter main body 14 by fitting the circumferential groove formed on the outer peripheral strain of the fitting convex portion 25 and the fitting convex portion 31 a. Is done. In this state, the ventilation closing portion 32 of the hood portion 31 is inserted into the recessed portion on the upper surface of the ventilation portion 13, so that the airtight (liquid tight) is blocked. At the same time, the inner side of the top surface 34 of the hood part 31 blocks the tip opening 12c of the spout part 12 in an airtight (liquid-tight) manner.

The present embodiment is configured as described above, and the adapter main body 14 made of a relatively high rigidity material, the spout part 12 made of a soft material, and the ventilation part 13 made of the same soft material are all integrally formed. Yes.
Therefore, the user simply unscrews the threaded portion of the adapter main body 14 from the container main body 11 during cleaning, and the adapter 15 in which the spout portion 12, the ventilation portion 13, and the adapter main body 14 are integrated, and the packing. 27 can be removed and the number of parts is extremely small, so that the cleaning operation is also easy. Similarly, since the assembly is very simple, it is very easy to handle as a whole.

In particular, when parts made of different materials are separately formed as in the conventional structure, tightening is possible only after proper assembly, and this is because of the demand for the function to be performed compared to sealing. Since the spout portion 12 and the ventilation portion 13 which are portions to be formed of a soft material and the adapter body 14 which is a portion to be formed of a material having a relatively high rigidity are integrally formed, there is a risk of liquid leakage due to an assembly error. There is no.
Further, as shown in FIG. 1 and FIG. 2, the spout portion 12 has a shape such as hardness suitable for an infant who has started to move from suckling, and the ventilation portion 13 is separated from the spout portion 12. When the infant inserts the spout part 12 into the oral cavity, it is easy to use because it can ensure the ventilation during drinking without blocking the ventilation part 13 with the upper lip etc. Excellent performance for drinking.

  Each configuration in the above-described embodiment may be implemented under a combination of different configurations, if necessary, by omitting a part thereof or replacing other configurations.
